仅提供摘要表格。随着风电进入电力系统的日益增多，运行备用指导方针需要修订，以确保系统安全。由于风电生产的不确定性，风电并网发电的备用管理一般是由常规电厂提供额外的备用余量。这样的策略不仅会增加运营成本，还会在频率事件期间施加额外的单位压力。本文提出了一种并入双馈感应发电机(DFIG)风电场的策略，以主动为频率控制提供一次备用。提出了根据可用风速进行风能储备分配的方法。开发了一个由传统机组和DFIG风电场组成的综合系统来评估频率响应和发电相互作用。最后给出了仿真结果，说明了该策略在备用调度中的优越性。
Summary form only given. With the increasing wind penetration into the power system, the guidelines of operating reserve need to be revised to ensure system security. Due to the uncertain characteristics of the wind production, the general way of the reserve management for wind integration is to provide additional reserve margin by conventional plants. Such a strategy could not only increase the operating costs but also impose additional unit stress during the frequency event. This paper presents a strategy that incorporates doubly-fed induction generator (DFIG) wind farms to actively provide primary reserve for frequency control. The wind reserve allocation according to available wind speed is proposed. An integrated system that consists of the traditional units and DFIG wind farms has been developed to assess the frequency response and generating interactions. Simulation results are discussed to illustrate the superiority of the presented strategy in reserve operation.
